I think he was trying to compare sequence vs. the other two constructs, the
pros/cons of the different constructs. To answer his question, that is the
point of xsd:sequence nodes, the enforcement of ordering. It's also the
typical default construct used for elements, since xsd:choice nodes or for,
well, choosing between one node of the group and xsd:all nodes have other
restrictions that most people have a hard time working around.
